Is it meant for Vellen to look like she is losing her hair at her age? Is that natural or could it be some side effect of a harsh medical treatment she had, like magical chemotherapy?

For someone from a race renown for their physical beauty like elves, that must be a very hard thing to endure. That is a really intriguing idea for a elven character! TBH I never really liked Vellen's bald design, but this puts a whole new spin on it! Well done!

The three were originally created from some random generator results, and among Vellin's characteristics was her being afflicted with an "incurable disease". I wasn't sure I wanted her to have such a disease, but that is where the inspiration for her being bald came from. But with the years, I figure yeah, maybe she is kind of sickly. I did have her get tired and unable to keep up with her two friends during the Zintiel chase scene!
The disease is generic and unspecified, but I imagine it's the reason behind her sparse hair, low stamina, and greyish skin tone._________________Félix
